WeChat official account "Shanhe Star Aviation" reported that on May 7, 2025, the SA750U large unmanned transport aircraft independently developed by Shanhe Huayu Aviation Technology and strategically promoted by Shanhe Star Aviation successfully completed the first domestic test of continuous autonomous parachute airdrop for multiple goods by drone.

This breakthrough is an important milestone in the development of China's large unmanned transport aircraft, providing key technical support for the unmanned delivery of materials quickly and in bulk under special scenarios.

During this flight test, the aircraft loaded with 1500 kilograms of airdrop items flew to the preset airdrop area and then autonomously completed a series of airdrop instructions. Multiple goods were sequentially smoothly released from the cabin, the parachutes unfolded one after another, and the goods accurately landed at the predetermined locations.

Throughout the entire airdrop process, the aircraft maintained a stable attitude, and the flight test was successfully completed.

The successful test of the SA750U drone intelligent airdrop system indicates that the company has fully and independently mastered a series of key technologies such as the drone airdrop system and the intelligent control of drone airdrops.

Several potential customers observed this flight test on-site and expressed high hopes for the timely market entry of this type of drone. We will complete the airdrop validation flights for more pallets and larger load capacities based on customer needs.

The aircraft will soon be put into practical use in typical application scenarios such as unmanned material delivery, emergency rescue, and feeder air logistics.

Since completing its maiden flight on August 22 last year, the SA750U large unmanned transport aircraft has completed dozens of sorties and multiple subject flight tests within three months. Subsequently, it took only four months for Shanhe Huayu to independently complete the development of the drone intelligent airdrop system.

The SA750U large unmanned transport aircraft was developed through systematic and in-depth market research by the R&D team, with demand as the driving force, using all-domestic systems and materials, and fully positively independently designed. The aircraft has a maximum take-off weight of 7500 kilograms, a maximum payload of 3200 kilograms, and a maximum range of 2200 kilometers.

The unique design features of the rectangular cross-section fuselage, large rear door of the tail, fixed landing gear, etc., enable it to have advantages such as rapid cargo loading and unloading, efficient unmanned airdrop, and wide adaptability of landing fields.

The development of the SA750U large unmanned transport aircraft has received strong support from the Hunan Provincial Department of Industry and Information Technology, the Hunan Provincial Department of Science and Technology, the Hunan Provincial Department of Finance, and the Zhuzhou Municipal Government.

The company actively responds to the major decision-making deployment of the Party Central Committee on creating new quality productivity in the low-altitude economy and targets the huge future demand for unmanned aerial material transportation and delivery. It is dedicated to developing the strategic product - the SA750U unmanned transport aircraft with a carrying capacity of up to 3 tons.

In the future, the company will seize the strategic opportunities of the low-altitude economic development, steadily launch a series of unmanned transport aircraft products with high intelligence, high safety, high reliability, and low cost, continuously meet market demands, provide core equipment that is self-controlled for the construction of China's low-altitude economy, and better serve the high-quality development of the low-altitude economy.

Hunan Shanhe Huayu Aviation Technology Co., Ltd. is a high-tech enterprise facing market demands such as material transportation, feeder air logistics, and emergency rescue, specializing in the development of intelligent unmanned aircraft. The core technology team, led by Chairman and Chief Expert Professor He Qinghua, adheres to the concept of pioneering innovation. With over 20 years of experience in the development of aviation equipment in the manned light aircraft and UAV sectors, they have led the development of several well-known general aviation products in China. The company owns key technologies such as overall aircraft design, rapid optimization iteration design of structures and strengths, medium and large UAV flight control, low-cost composite material forming and manufacturing, and airworthiness certification, and has obtained more than 30 core patents.

The SA750U multi-purpose large unmanned transport aircraft currently under development by the company is being built using all-domestic systems and materials, filling the gap in domestic large unmanned transport aircraft with a payload of 3 tons.
